Bob Dylan plugs the 2008 Cadillac Escalade

You know the times are a-changin' when you see Bob Dylan in a commercial for the Cadillac Escalade. In an ad campaign beginning today with a 30-second TV spot, the counterculture icon is shown driving across the desert behind the wheel of the '08 blingmobile in an effort to highlight its as-standard XM Radio. Dylan hosts his own "Theme Time Radio Hour" show on XM, which will this week feature a Cadillac-themed episode.

In today's press release, Liz Vanzura, Global Marketing Director for Cadillac, said that the automaker was "pleased to join XM in this exciting campaign that brings together two great American icons--Cadillac and Bob Dylan--to reinforce the unparalleled XM listening experience available as a standard feature in every Cadillac."

Look out for print and online advertising to follow the TV spots sometime in November.
